Requirement, additional heat source KP1

Part no. 7387 905
Function
The additional heat source supplies, individually or jointly with the
boiler, heat to the cylinder. This is designed as a low loss header.
Taking into consideration the inertia of the boiler, control is carried out
so that the additional heat source covers the peak load and the boiler
covers the base load. In the operating phase of the additional heat
source, the boiler pump is operating and the control unit of the boiler
mixer is enabled.
Standard delivery:
■ Sub-menu on touch-screen
■ Motor protection, boiler circuit pump, additional heat source
■ Control of motor, shut-off device
■ Zero volt contact for the control of the burner
■ Sensor PT-1000 incl. sensor well ½" x 280 mm (installation, return
of additional heat source)
■ Sensor PT-1000 incl. sensor well ½" x 280 mm (installation in low
loss header - system sensor)
Note
The electrical output data of the on-site boiler pump (kW, Ampere,
Volts) must be given.
